During storms, they flew a research aircraft with several powerful instruments, including one that can identify the
type of particle in a cloud and determine whether it was dust or some other
type of aerosol.
Volcanic events and some
types of human - made pollution, both
of which inject sunlight - reflecting
aerosols (i.e., tiny
particles) into the atmosphere, lower temperature and are examples
of forcings that drive decreases in temperature.
Among these are the gases methane and ozone, and several

of cloud
particles interacts with
aerosol particles and evolves with time.
In addition to the data from the radiometers, the Berkeley Lab scientists will get supplemental data by taking advantage
of a separate, in - depth DOE climate study at the same location, which is using additional instruments and a balloon - borne sounding system to get information on temperature, cloud cover, the density and
types of aerosols or pollution
particles, heat fluxes and other climate variables like precipitation.
Freshly emitted soot is an example
of a hydrophobic
aerosol type; after chemical transformation in the atmosphere (e.g. oxidation
of its surface rendering it more hygroscopic; condensation
of more hydrophilic species onto the
particle) it will gradually pick up water as well.
